ODroid GO Tricorder Project reaches custom PCB Phase

    ODroid created a fantastic Product with the ODroid GO. A nice compact device with an LCD, Buttons, Speaker, a ESP32 from Espressif AND an expansion board. Although the Hardkernel Wiki already gives examples how to use the device for your own hardware projects, it seems that almost all people regard it as a […]

Playing around with Odroid-GO

Odroid GO is a fantastic device for those dealing with espressif chips (8266/ESP32). While the big focus is on gaming, the device also got a 10 pin expansion header to support I2C and SPI. Having a build in graphical LCD and several buttons, this makes the device an ideal playground for own projects including own […]

Based on the Atom Editor (Well, not my primary choice of editor because its too slow, but for that environment fine) check it out here…

Clock with Timer

Another little project is this one: An LED Clock driven by an ESP8266, using those 8×8 LED Matrix components: In principle very easy. The ESP is programmed with Arduino, using a NTP Library and a Library for the Matrix LEDs. The only tricky part was to reprogram the Matrix Library because each of the […]

ESP32 arrived

I am an absolut fan of the ESP8266 in its various forms. It is really cool to build things with it. A device with Wifi, several IO Pins and programmable via C or Arduino is a perfect match for small devices. The biggest drawback of such a device is: In order for the Wifi to […]

RS232 / Bluetooth Adapter

This is the first prototype of a RS232 / Bluetooth adapter. Its design is quite simple: Use a standard MAX232 circuit and connect the ttl out/inputs with an HC05/06 bluetooth transceiver. Although some MAX232 seem to work with 3,3V I had bad experiences with it so I drive the MAX with 5V and the HC05/06 […]
